The way I see it, besides a VERY few possibly legit guys, the only Catch wrestling you're going to learn in North America is going to come from guys who went to Japan and were taught by some of the Shooto or Pancrase, etc type of guys.

Whether or not Catch Wrestling is related to Asian grappling arts or not doesn't matter. The only thing that matters is whether or not it works. Besides, any grappling is going to be related somehow, there are only so many ways to bend a limb and all. The main difference isn't so much in the techniques (outside of perhaps a few subtleties), the main difference is strategy. If it works, it works and it doesn't matter where it came from.

Tony Ceccine(sp?) is supposedly the primary legit source for catch in the US.

I've trained at different times with 2 of his students. Catch is very cool and works the positions differently than BJJ which makes it interesting. My biggest problem with it is it can come accross a gimic style because it works best against beginners. And a lot of the techniques are stopped by good BJJ guys.

However I think it may be more of a skill difference more than any technique problem.

Hmm "Unique Positional Strategy" eh? Sounds a little grandiose. Basically they don't preach position before submission as much as BJJ and MMA. Their theory is they can hurt you from any position and even if they don't get a submission with the move they can use it to change positions. Lurkers, feel free to correct me if I misinterpret this but that's what I got from both the guys I trained with.
